    摘要: Systems and methods for noncontact ablation of tissues or materials in/on the body using an ablation catheter that has a directional ablation unit. The ablation unit has a set of individual transducer (e.g., ultrasound) elements that are movably positioned. A position adjustment element (a deformer) is movable with respect to the ultrasonic transducer to alter the positions of the individual transducer elements and thereby alter the directions in which the transducer elements emit ultrasonic energy. In one embodiment, the ablation catheter is a lumen catheter through which a positioning/measurement catheter can be inserted. The luminal ablation catheter is inserted through the skin and into the body via conventional methods. The ablation and positioning catheters can be used to make electrical measurements with respect to the surrounding tissue, and the ablation catheter can be used to emit energy in a desired direction and/or pattern to ablate target tissue.

    摘要: A tool unit applied to ultrasonic machining, includes an amplitude transformer, a machining head and a connecting portion. The machining head has a micron-sized array structure. With the connecting portion, the amplitude transformer and the machining head are assembled together and the connecting portion has a change in shape. The machining head includes a substrate and at least one diamond layer. An upper surface of substrate touches the amplitude transformer or the connecting portion. And the diamond layer is disposed on an lower surface of substrate. The material of the substrate is selected from a group of a steel material with thermal expansion coefficient ranged from 10.70×10−6K−1 to 17.30×10−6K−1, tungsten carbide and combination thereof. The material of the diamond layer is selected from a group of a diamond material with thermal expansion coefficient ranged from 1.00×10−6K−1 to 2.50×10−6K−1, a polycrystalline diamond, a diamond sintered body and combination thereof.
